Paper Abstract

The Near Infrared Camera for the James Webb Space Telescope is designed to operate at a temperature of 37K. The instrument must be assembled and aligned at room temperature. The optical design is refractive and incorporates several different lens materials in addition to several mirrors which make an athermal design very difficult. All of the instrument components are designed so that the instrument can come into alignment at 37K after assembly at room temperature. The methods to predict alignment shifts are presented in this paper.
